Online bass tuner

Tune your bass straight from your browser with the microphone, free and with nothing to install. Standard tuning on a four-string bass is E-A-D-G: the same notes as the four lowest strings of a guitar, but one octave lower. If you play in Drop D, Drop C or a half-step down, pick it in the selector.

How to use it

Same as with the guitar: choose the tuning, allow microphone access and play an open string. On bass it helps to pluck firmly and wait a moment, because low notes take a little longer to settle and the tuner needs that instant to read them cleanly.
